Collaborative computing of parallel applications in P2P environments

Published in NEA 2015, 2015

Abstract

This book addresses the issue of “How to explore collaborative computing in P2P Grids to run BSP applications efficiently?”. To answer this question came the BSPonP2P model, which creates an environment with approaches based on the structured and unstructured models from the P2P networks. The combination of these models aims to streamline the management of communication and data on the network. Another difference of the proposed model is the use of the parallel programming model Bulk Synchronous Parallel (BSP), which creates an environment for executing processes, validating dependencies and improving communication between them. We use metrics required for the processes as memory, computing, communication, and also information from the infrastructure to establish a unique performance metric called PM. This metric is evaluated periodically to define migrations according to the launched superstep barriers. The results show that BSPonP2P uses the computational idleness, and brings performance gains to the executions.
